From the spinning pri eiple appli'e'gi t6 this dvice iollo'w tliit the speaz relative to the spinning ring are very low and amount to only a very slight fraction of the speed of the traveller when the ring is stationary. This means that wear of the traveller will be extremely slight and the consumption of travellers be reduced to at least one-tenth.

It was assumed that the ring and the spindle rotate at the same speed, but this is not advantageous, and it is better to have the rings lead slightly so as to effectively prevent the spindles from leading when starting the frame owing to slipping of the belt etc. This would make theyarn too tight and result in breaking all threads, and this danger can be avoided by letting the rings lead slightly. The arrangement can also be utilized for nosing by slightly braking the'gearing of the spinning rings every time the ring rail is in its highest position and thereby causinga slight increase in the tension'of the yarn.

According to the known ring spinning principle it is impossible to spin on spindles of small diameter, to say nothing of spinning on bare spindles, as the radial tension applied to the yarn increases hyperbolically in proportion to the reduction of the diameter of the bobbin and causes the yarn to break. This injurious effect of radial tension on the yarn is avoided in the present arrangement and utilized for the regulation a of winding so that the tension of the yarn remains constantduringthe entire spinning processregardless of thediameter of winding .or, in other words, that the balloon,the visible criterion of the tension of the yarn, has always the same size. The result of experiments made confirms this statement, no appreciable change in the balloon being noted whether spinning took place on a bare spindle or any other winding diameter.

It follows from what has been said above that not only can spinning take place on the bare spindle but that working with very slight twists becomes possible, i. e. that any yarn of soft twist can be used. Furthermore, in fixing the speed of the spindle one is nolonger dependent on the tension of the yarn at present connected with even the smallest diameter of the bobbin but one may choose any speed the yarn in question will stand; the maximum speed obtained in ring spinning framesl aving a variable spindle speed can be constantly maintained.

In order that the invention may be more readily understood one embodiment of the same is, by way of example only, illustrated in the accompanying drawings, in which:

The roving bobbins 1 are secured to a creel 2 arranged on the frame 3 and the supports. On the support 4 is arranged the so-called drawing mechanism 5 through which the slubbing of the roving bobbins l is drawn out, i. e., refined, and whence it passes through the thread guide wires 6 to the spindles 7 while the thread is guided by travellers arranged on the rings 8. The rings 8 rest on the ring rail 9, and by means of the taller legs 10, a ratchet motion 1.1, a tension roller 12, a chain'13 with segment 14. a raising and lowering motion is produced, the final position of the ring rail approaching increasingly its initial position in order to insure an'inereasing circumference of the bobbin. The spindles 7 are secured to the spindle rail 15, and each movable part of the spindles is provided with a wharve 16 which is caused to rotate. The motion of the frame is taken up by the pulleys 17 in a three-fold manner. In the first place, the rotation is taken up to operate the drawing rollers 5, which is of no interest here and therefore omitted, second, the rotation for the spindles, and third, for the rings. The rotary motion for the from the shaft18 carrying the pulleys 17 by means of two pulleys 19 andQO arranged on the shaft. Over these pulleys 19 and 20 runs a belt 21 which is endlessand which runs from the pulley 19 over a snatch block 22 along the outside of the spindles 7, passes by means of two additional snatch blocks 23 attached to the frame 26 to the other side of the spinning frame where it also runs along the spindles 7 and is guided to the pulley 20 over a snatch block 24. The belt passes around this pulley and then runs over the "snatch block 25 past the back of-the spindles. On'the frame 26 it is guided to the other side of the said frame by means of the snatch blocks 27 where it runs again behind the spindles while touching them and is guided back to the pulley 19 by means of the snatch block 28. The frame 26 is provided with a tension appliance 29 and a ten} sion roll 30 set by means of a hand wheel 31 and a spindle 32 in order to cause the driving means 21 to touch the spindles tightly. The spindles and driving means as shown in Figs. 5 and 6 are as follows:

On the spindle is found a wharve 1,6

spindles is taken up against which a roll 33 presses yieldingly. The rims 34 of this roll overlap the wharve 16 of the spindle 7 and thus keep it in position. Between the wl'iarve 16and the roll 33 passes the driving means 21 which 011 its return touches thewl'iarve 16 on the back. The rolls 33 are attached to one-arnied levers 35 which are pivotally arranged at 36. These rolls as better shown in Fig. 61 are preferably alternately mounted on each side of the spindle frame, and urged towards the spindle 7 through springs 37, thus serving 'as a spring actuated guide for the driving belt 21 while supporting the spindles 7 by means of'flanges 34 engaging the wharves 16. To facilitate their movement the rolls 33 are provided with ball bearings 38.

The drive for the rings is constructed in a similar manner, except that it slides vertically with the ring rail. For this purpose the following arrangement is provided. The driving shaft 18 carries a bevel gear 39 in mesh with two other bevel gears 40 which transmit the drive by means of the shafts 41 to the bevel gear 42 on the sides of the frame. These bevel gear wheels 42 are connected with the bevel gear wheels of a vertical shaft 43 on which a pulley 45 with the ring rail slides up and down over a key 44. From this pulley 45 the belt 46 passes along the front side of the ring rail over a tension roll 47 at the end of the rail to the back of the latter and returns to the pulley 45. This belt 46 does not touch the rings directly, but between every two rings 8 are provided in front and in rear, the rolls 48 which touch the rings and which in turn are touched by the driving means 46. The latter is pressed against the intermediate friction rolls 48 by means of spring-actuated tension rolls 49 alternately mounted on each side of the ring supporting frame. All rolls and rings may run in ball bearings to facilitate their movement. The rings 8 are arranged in a sleeve 50 provided at its bottom side with a roller 51 and a fastener 52 for fastening. Aturn of the sleeve 50 will also rotate the ring, and the ring carries the traveller 53 through which the thread is guided to the bobbin. The traveller 53, with its outer member 54, supports a thin disk 55 which is freely adjustable and which can swing according to the speed of the ring and the traveller. If the speed is great enough, the disk 55 will completely bug the upper side of the ring 8 and not brake the traveller at all. If the speed decreases, the disk 55 will be lowered and, if the retardation continues, rest on a rough lining 56 to increase the braking of the traveller 53 as shown by the dotted lines when the ring rail is in its highest position, and this retarding of the ring relative to the spindle will bring about the tight winding of the noses as mentioned before.
